Crunches have a long-standing history as the gold standard of ab exercises. But, unlike crunches, which isolate your rectus abdominis, planks activate your entire core, from your deep stabilizing ...
Sit-up form. The sit-up is an abdominal endurance training exercise to strengthen, tighten and tone the abdominal muscles.It is similar to a curl-up (that target the rectus abdominis and also work the external and internal obliques), but sit-ups have a fuller range of motion and condition additional muscles.
The crunch or curl-up is an abdominal exercise that works the rectus abdominis muscle. [1] It enables both building and defining "six-pack" abs and tightening the belly. Crunches use the exerciser's own body weight to tone muscle and are recommended by some experts [ like whom? ] , despite negative research results [ citation needed ] , as a ...
The leg raise is a strength training exercise which targets the iliopsoas (the anterior hip flexors).Because the abdominal muscles are used isometrically to stabilize the body during the motion, leg raises are also often used to strengthen the rectus abdominis muscle and the internal and external oblique muscles.
Kaiser said traditional crunches can't effectively target the body's deep core stabilizers — the muscles in our mid-section (like the transverse abominis) that can help our core "appear flatter."
Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).
